4x+18y=12

  • algebra - ,

    Take the first equation and solve for x:
    2x-9y=2
    x=(2+9y)/2
    Substitute this value of x into the second equation and solve for y.
    Substitute the solution for y into the first equation to find the solution of x.
    BACK SUBSTITUTE x and y into both equations to make sure the answer is correct.
